@RadioRoslyn, Heathkit must have gotten a good deal on a lot of tubes. I had (and still have) in my archeological dig (Garage) several Heathkit amps, including the entry level A7 which has 12V tubes (12A6s right out of ARC5 receivers, 12SN7s, etc), many branded "JAN" (Joint Army Navy) Gov't surplus. I'm sure that they saved money buying them, but I wonder if they had to blow coin on power Xformers with 12V heater windings. The more premium amps had premium tubes like Tung Sol 5881s, Genelex KT66s (I wish I had a few pairs of them) and Tung Sol 6550s (I wish I had a slew of them, the real original USA ones, not the foreign reissues) Unfortunately, I have no true "pairs" but have at least 1 each of the A7, W-3M, W-4M, W-5M and W-6M that I have to restore, or at least fix up.
